Introduction
2001 Energy SxS models are being introduced in response to the requirement for more energyefficient refrigerators by mid year 2001, along with having feature and operation enhancements. The primary differences in this refrigeration system are the adaptive defrost system (see Pub. # 31-9062), control board, software, and control systems that operate independently in fresh food and freezer sections. The new high-efficiency control system has the ability to cycle components and adjust fan speeds as required to maintain temperaturesetting ranges in freezer and fresh food sections. Feedback systems are digital inputs and relay outputs. Sensors (thermistors) are used to measure temperature with communications to a main PC board, which controls the unit components. The refrigerator has versions that have control knobs or touchpads (Profile models) to provide inputs to a microprocessor. The freezer/ fresh food controls are temperature setpoint type and have settings of 0-9 with 9 being the coldest temperature possible. The new NO CLEAN condenser is serviceable from the rear and is designed to prevent the customer from having to clean the condenser in normal usage conditions. Sealed system operation and compressor are functionally the same as previous models, with some minor changes. The 20', 22', and 25' side-by-side models are the models affected. These models are available with through-the-door chilled water and ice dispenser, and built-in water filter feature. On models requiring icemaker, the newest electronic icemaker (see Pub. # 31-9063) has been or can be installed. The freezer has adjustable shelves, slide-out Spillproof shelf, QuickSpace shelf, and deep door shelves, based on model. The fresh food section has a baking soda holder, fruit and vegetable drawer, drawer dividers, adjustable humidity drawer, and convertible meat drawer. This new high-efficiency refrigerator is a combination of the most efficient refrigeration system and the most desirable customer features available.

IMPORTANT: PLEASE READ CAREFULLY
FOR PERSONAL SAFETY, THIS APPLIANCE MUST BE PROPERLY GROUNDED.
The power cord of this appliance is equipped with a three-prong (grounding) plug that mates with a standard three-prong (grounding) wall receptacle to minimize the risk of electric shock hazard from this appliance. The customer should have the wall receptacle and circuit checked by a qualified electrician to make sure the receptacle is properly grounded.

MAKE SURE PROPER GROUND EXISTS BEFORE USE TEMPORARY METHOD (Adapter plugs not permitted in Canada)

Where a standard two-prong wall receptacle is encountered, it is the personal responsibility and obligation of the customer to have it replaced with a properly grounded three-prong wall receptacle. DO NOT, UNDER ANY CIRCUMSTANCES, CUT OR REMOVE THE THIRD (GROUND) PRONG FROM THE POWER CORD. USAGE SITUATIONS WHERE THE APPLIANCE’S POWER CORD WILL BE DISCONNECTED INFREQUENTLY Because of potential safety hazards under certain conditions, we strongly recommend against the use of an adapter plug. However, if you still elect to use an adapter, where local codes permit, a TEMPORARY CONNECTION may be made to a properly grounded two-prong wall receptacle by the use of a UL listed adapter which is available at most hardware stores. The larger slot of the adapter must be aligned to provide proper polarity in the connection of the power cord. CAUTION: Attaching the adapter ground terminal to the wall receptacle cover screw does not ground the appliance unless the cover screw is metal, and not insulated, and the wall receptacle is grounded through the house wiring. The customer should have the circuit checked by a qualified electrician to make sure the receptacle is properly grounded. When disconnecting the power cord from the adapter, always hold the adapter with one hand. If this is not done, the adapter ground terminal is very likely to break with repeated use. Should this happen, DO NOT USE the appliance until a proper ground has again been established.

ENSURE PROPER GROUND AND FIRM CONNECTION BEFORE USE

USAGE SITUATIONS WHERE THE APPLIANCE’S POWER CORD WILL BE DISCONNECTED FREQUENTLY Do not use an adapter plug in these situations because frequent disconnecting of the power cord places undue strain on the adapter and leads to eventual failure of the adapter ground terminal. The customer should have the two-prong wall receptacle replaced with a three-prong (grounding) receptacle by a qualified electrician before using the appliance.

Normal Operating Characteristics That Are Different from Previous Models • • •
Icemaker auger rotates clockwise. Evaporator fan running, without compressor or condenser fan. Post Dwell (Adaptive Defrost), compressor, and condenser fan on with evaporator fan off after defrost cycle. Liner Protection Mode, fan comes on when the doors are open for 3 minutes. Evaporator fan and compressor can run continuously for 2 hours (Adaptive Defrost). Different sound levels can be heard when the fan changes speed. Response time for drastic temperature change is 2 to 10 minutes. The main control board will only respond to 8 degrees (Fahrenheit) of temperature change per minute as determined by resistance of sensor.

• •

Length of time the compressor has run since the last defrost cycle. Amount of time the defrost heaters were on in the last defrost cycle.

Cooling Operation (Adaptive Defrost)
During the cooling operation, the main control board monitors door opening (fresh food and freezer doors) and compressor run times. The board counts the time the doors are open. It reduces the length between defrosts by 255 seconds (multiplication factor) for each second that each door is open. If both doors are open, it reduces it by twice the amount. The multiplication factor reduces compressor run time. If the doors are not opened, the compressor will run up to 60 hours between defrosts. If the doors are opened frequently and/or for long periods of time, the compressor run time between defrosts will be reduced to as little as 8 hours.

Pre-Chill Operation (Adaptive Defrost) Adaptive Defrost
Adaptive Defrost can be described as a defrost system that adapts to a refrigerator’s surrounding environment and household usage. Unlike conventional defrost systems that use electromechanical timers with a fixed defrost cycle time, Adaptive Defrost utilizes an intelligent, electronic control to determine when the defrost cycle is necessary. In order to accomplish the correct defrost cycle time, the main control board monitors the following refrigerator operations:
F R E E Z E R A I R

Length of time the refrigerator doors were open since the last defrost cycle.

When the main control board determines that defrost is necessary, it will force the refrigerator

into a continuous cool mode (pre-chill). During prechill, the freezer temperature may be driven below the set point. However, the fresh food temperature will be regulated by the damper. Pre-chill will last for 2 hours. These models do not have a defrost holdoff.

Liner Protection Mode
The liner protection mode will activate if either of the doors have been open for 3 minutes. This mode will start the evaporator fan and close the damper. This mode is controlled by 2 timers. Timer #1 monitors door-open time. A 3-minute door-open count begins when the door is opened. If 3 minutes elapse before the door is closed, the liner protection mode will become active. Once the door is closed, timer #1 resets and liner protection mode goes into standby. In standby, normal fan and damper operations resume and timer #2 begins a 3-minute door-closed count. If 3 minutes elapse without a door opening, liner protection mode will completely deactivate. If a door is opened within the timer #2 door-closed count, the remaining time in the door-closed count will be deducted from the timer #1 door-open count.

Defrost Heater Operation (Adaptive Defrost)
After 2 hours of pre-chill operation, the main control board turns off the compressor, condenser fan, and evaporator fan. During defrost operation, the main control board monitors the evaporator temperature using evaporator thermistor inputs. The thermistor will terminate defrost heater operation in less than 45 minutes. Typical defrost time is 20-30 minutes. Maximum defrost cycle is 45 minutes with heater on, 5 minutes in dwell. The defrost system is protected by a defrost safety thermostat (switch). The thermostat opens when the evaporator temperature raises to 140° F and closes when the evaporator temperature lowers to 110° F.

Dispensing Functions
The water, crushed ice, and cubed ice functions are controlled by the main control board. To select a function, press the appropriate pad on the dispenser. The LED will light to identify the selection. To dispense the selected item, depress the dispenser cradle located in the dispenser recess. The solenoid and linkage assembly will open the ice chute door to dispense the ice. If cubed ice is selected, the crushed ice bypass solenoid will allow cubed ice to bypass the ice crusher. The ice chute door must remain open for 5 second after dispensing ceases. After this 5 second delay, the solenoid and linkage assembly will shut the ice chute door. The dispenser light will come on automatically when the dispenser cradle is depressed and will fade out 5 seconds after it is released.

Dwell Period (Adaptive Defrost)
After defrost heater operation has been terminated by the main control board, a 5-minute dwell period occurs. During this period, the compressor, condenser fan, and the evaporator fan remain off. The remaining frost melting from the evaporator will continue to drip and drain so that prior to the cooling operation, the evaporator will be totally clear of any moisture. After the 5-minute dwell period, the unit goes into post dwell.

Post Dwell (Adaptive Defrost)
The post dwell period is designed to cool the evaporator before circulating air within the refrigerator. This prevents any residual heat on the evaporator from being distributed in the freezer. During this period, the compressor is on and the condenser fan is on, but the evaporator fan is off, and the damper is closed. Post dwell lasts 10 minutes on these models.

Dispenser Light
The LIGHT pad turns the dispenser light on and off. When the light is turned off, it will fade out. The dispenser light will come on automatically when the dispenser cradle is depressed and will fade out 5 seconds after it is released. The LIGHT pad will not turn off the light during dispense.

–9– For more help, see Samurai Appliance Repair Man at www.FixitNow.com.

Dispenser Lock
When the dispenser system is locked, no dispenser command will be accepted. This includes the dispenser cradle and will prevent accidental dispensing that may be caused by children or pets. If a pad is pressed with the system locked, it will be acknowledged with 3 pulses of the LOCK LED accompanied by an audible tone. To lock or unlock communication between the dispenser and main control board, press the LOCK pad and hold it for 3 seconds. The LOCK LED will flash while the LOCK pad is pressed. When the communication is locked, the LOCK LED will be illuminated. The status of other functions selected prior to the initiation of the lock feature will be displayed. If the lock is engaged while a mode is active, the LED will remain on until that mode times out. If the lock is engaged when the filter timer expires, the LED will come on but cannot be reset until the lock is turned off. The lock feature will be restored in the event of a power disruption.

Hinge System and Door Closure

Cam with Thimble Screw Cam Riser Hinge Adjustment Pin Hinge
GEA00909

The hinge brackets are not adjustable on the cabinet. The fresh food door can be adjusted up and down by using the hinge adjustment pin (located on the fresh food lower door hinge). The fresh food and freezer lower door hinges are equipped with replaceable cam risers. The cam risers assist in door closure. If the fresh food door is adjusted too high, cam riser will not be engaged, and the fresh food door will not close properly. IMPORTANT: The refrigerator rollers must be adjusted correctly for proper door closure. When the rollers are adjusted correctly, the door should close easily when open approximately 45 degrees (halfway)

Filters
Some models are equipped with a water filter located in the upper right-hand corner of the fresh food compartment. The filter is designed to be used for up to 8 hours of open valve time or 1 year of calendar time. When 90% of filter time (dependant on model) has elapsed (open valve time or calendar time, whichever comes first), the main control board will illuminate the filter reminder LED (amber). When 100% of the filter time has elapsed, the main control board will illuminate the filter reminder LED (red).

Airflow (Cabinet Interior)

“Jelly Roll” Condenser

The freezer compartment is designed so that when the evaporator fan is operating, air is drawn into the bottom of the air tunnel and through the evaporator. The cold air is then pushed out into the top of the freezer. The fresh food compartment receives chilled air via an electronic damper positioned at the top, rear of the refrigerator between the freezer compartment and the fresh food compartment. The damper is controlled by the main control board and when open, allows chilled air from the freezer air tunnel to move into the fresh food compartment. Air returns from the fresh food compartment to the freezer compartment via a vent located to the left of the FRESH PRODUCE drawer.

The new NO CLEAN condenser is accessed from the rear and is designed to be tolerant of up to 2 inches of lint. The idea is that the consumer, in normal operating conditions, will never have to clean the condenser. If necessary, only an ordinary appliance brush is used. Air is drawn in from the outside diameter of the condenser and pulled out by the condenser fan. A condenser fan baffle is located at the rear to direct airflow through the condenser. Functionally, the condenser does the same job as previous models. Air is drawn in from front left and rear left and exits out front right side of refrigerator.
